People vs. Martinez y Angeles
Case
G.R. No. 191366
Decision Date
Dec 13, 2010
Accused acquitted as illegal arrest, broken chain of custody, and inadmissible evidence failed to prove guilt beyond reasonable doubt.

Case Summary (G.R. No. 191366)

Applicable Law

1987 Constitution, Article III, Section 2 (protection against unreasonable searches and seizures)
Republic Act No. 9165 (Comprehensive Dangerous Drugs Act of 2002), Sections 11, 13, and 21

Factual Background

On September 2, 2006, at about 12:45 PM, a confidential tip reached Police Community Precinct II that a “pot session” was underway in Rafael Gonzales’s residence. Officers proceeded without a warrant. At the gate, they arrested one occupant leaving through a side door. Inside, they found the four other respondents in a room with open plastic sachets and used aluminum foil allegedly containing shabu residue. All were arrested; paraphernalia and residues were seized and submitted for laboratory examination.

Prosecution’s Evidence

– Testimony of PO1 Azardon: entry based solely on an anonymous tip, discovery of sachets and foil in plain view, arrest of all occupants.
– Seizure turned over to P/Insp. Maranion, who conducted chemical analysis: 115 sachets, 11 rolled foils, and 49 cut foils tested; all sachets, 11 rolled foils, and 27 cut foils positive for methamphetamine hydrochloride.
– Drug tests on accused (except the first arrestee) were positive for methamphetamine use.

Defense’s Account

Respondents argued they were wandering in the subdivision seeking a paint supplier, not engaged in any pot session. They denied knowledge of the seized items and claimed the police planted paraphernalia.

Ruling of the Regional Trial Court

The RTC found the four appellants guilty beyond reasonable doubt of Possession of Dangerous Drugs During Parties, Social Gatherings or Meetings (Sec. 13 in relation to Sec. 11, RA 9165). Each was sentenced to life imprisonment, ₱500,000 fine, and forfeiture of seized items. The case against the first arrestee was dismissed.

Ruling of the Court of Appeals

The CA affirmed the RTC, concluding constructive possession was sufficiently proven. It acknowledged minor lapses in compliance with Section 21 chain‐of‐custody rules but held the integrity and evidentiary value of the seized items were nonetheless preserved.

Issues on Appeal

  1. Legality of warrantless entry, arrest, and search
  2. Sufficiency of probable cause based on the tip
  3. Inadmissibility of evidence obtained from an illegal search
  4. Breakdown in the chain of custody of seized items

Analysis – Unlawful Arrest and Seizure

– No valid exception to the warrant requirement applied: the anonymous tip lacked indicia of reliability or personal knowledge.
– The officers had no personal knowledge or basis for probable cause to enter, arrest, or seize.
– Plain-view doctrine inapplicable: there was no prior lawful intrusion, and the discovery was not truly inadvertent.
– Under Article III, Section 2 of the 1987 Constitution and Rule 113, warrantless arrest requires probable cause grounded on personal observations or circumstances; neither was present.
– Evidence seized during the illegal entry is inadmissible as “fruit of the poisonous tree.”

Analysis – Chain of Custody

– Section 21, RA 9165 mandates immediate inventory and photography of confiscated items in the presence of the accused (or counsel), media, DOJ representative, and an elected official. No such inventory or photographs were made.
– Seized items were not properly marked at the time of confiscation; l
